Cancer will overtake heart disease as the world's top killer by 2010, part of a trend that should more than double global cancer cases and deaths by 2030, international health experts said in a report released Tuesday. Rising tobacco use in developing countries is believed to be a huge reason for the shift, particularly in China and India, where 40% of the world's smokers now live.

When actress Christina Applegate announced she had had a double mastectomy this summer, she also said she had begun immediate reconstruction surgery. But recent data suggest fewer than 20% have immediate reconstruction after a mastectomy.
